ELECTRIC HEADLIGHT.

Application led July 12, 1924. -SerialNo. 725,568.'

My invention relates to' a headlight including carrier and battery forthe same;

arranged in such a manner that it may be conveniently attached to theoperators head around automobiles and other machinery,

as it leaves both hands of the operator free Jand directs the light'exactly on the parts to be operated upon. as a miners'lamp.v

In. the accompanying drawings, one embodiment of the invention isillustrated, and

Figure 1 is a front elevation of the device as attached to an o eratorshead and body;

Fig. 2 is a top p an view of the head set with the lamp; v

Fig. 3 'is a detail section through the ball and socket joint; l Fig. 4is a section on the line 1 --4Eof Figure 1 showing the battery box;

Fig. 5l is'a fragmentaryend elevation of the box, and

Fig. `6 is a' section on the line 6-6 of Figure 2.

fn the drawings, the reference nummeral 10 represents the head set ofthe device and 11 the battery box for the velectric lamp. The head setconsists ofv a shield12 to which is attached, as by rivets 13, aresilient clip 11 having forwardly directed arms terminating wlthsemi-spherical ball sockets 15.

By means of aset screw and wing nut 16,

the arms 14 may be drawn together in order to clam the cups or sockets15 around a ball 17 whic is rigidly secured tothe lamp car'- rier 18, asbest seen in Figure2. Between the cups and the ball are preferablyprovided packings 29 of some pliable material, such as leather orrubber. The lamp carrier is of any suitable construction provided withlens 19 in front of the electric lamp 20.

The shield 12 which is preferably made It may. also be used the linings21 and 22. From the top el the shield l2 extends 'rearwardly a top strap2 6 also stitched to the linings 21 and 22 and provided with a buckle 27forlengthening or shortening the same. The -rear end of the to strap hasa loop 28 which is taken aroun the side strapl 23 inI order to haveslidable engagement therewith.

The reference numeral 30 `'represents a double conductor for the lamp 20which continues from the samein upward direction through an eyelet 31near the upper end ofthe shleldJ through a second eyelet 32 onl theupper side of top strap 26 andthrough a third eyelet 33 on the sidestrap 23.v The other end of the double conductor 330 is taken to thebattery box 11 and connected with the cells 34 therein. In Figure 4abattery box con aining two cells has been shown but it is evident thatany number of cells may be provided according to thestrengthof thelighty in the lamp. The battery box has a hinged lid 35 held down by iaclasp 36` and at one end of the battery box is'furnished' a switch 37which,l

when swung in one direction, contacts with the terminal 38 and ifswungin the opposite dil'ectionwill be locked by a'clamp39 when nocurrent is furnished for the lamp 20.

4A shoulder strap- 40 is secured on the battery box, as best seen inFigure 1, so that the operator may 'conveniently carry the battery. boxon one side or on his back; The reference numeral 41 designatesabeltsecured to the battery box and adapted to be taken around the operatorsbody to hold the box firmly thereon.

By means of-the ball and socket joints 15 and 17 and the clamping screwv16, it is possible to adjust the position of the lamp in the directiondesired so that it may point not only straight ahead of the operator butat any angle upwards, downwards 'or sideways as he may desire.

Having thus described the invention, I claim:

A headlight device comprising an elonof springsteel and curved to thecontour' gated plate curved longitudinally to conof the forehead of theoperator is rectangu lar-in shape and embedded between the inform to theforehead, a'casing for said plate formed of front and rear strips ofVgreater dimensions than saidV plate and having their edge portionsextending from theplate and joined ther, said front. stri being formedwith an openinginterme 'ate its' length and width, aheadencircling-strap set @ma .a one end a me and of mdin',

a fastener connected with the other end of said casing and adapted foradjustable engagement with the free end of said strap to vhold the straptightly about the head, an upper. strap for extendingv over the headhaving its forward end secure-d to said casing intermediate the ends ofthe casing and havin its rear end provided with a loop: to slidablyreceive said head encircling strap, a U-sliaped bearing bracket securedto said plate within the opening-of the front strip and having. its armsprojected lforwardly 'from `the plate and casing .and terminating insocket-forming-cups, a lamp including 'a casing and a shank extendingrearwardl?I '15 1 f for tight gripping of the ballbetween the 20 cups. ei Y In testimony whereof I affix my signature.
